cocaine UTENSIL.

Specicaton of Letters Patent'.

Patented Mar. 11, 1913,

Application led anuary 19, 1912-. Serial No. 672,207.

To all whom4 it may concern Beit known that l, CHARLES D. FRAUN- FELTER, a citizen of the United States, and a resident of the city of Zanesville, county of Muskingum, and State of Ohio, have invented certain new and useful Improvements in'Cooking Utensils, of which .the following is a specification.

My invention relates toimprovements in cooking utensils and has for .its object the provision of a cooking utensil of improved construction and o eration and especially adapted for use in reless' cookers.

The invention4 consists in the combinations and arrangements of parts hereinafter described and claimed.

" Theinvention will be best understood by reference to the accompanying drawing forming a part of this specilication, and which is a perspective View, with portions f broken away and shown in section, of a cooking utensil embodying my invention.,

:The preferred form of construction as j illustrated in the drawing comprises an outer cylindrical metallic shell 1 havingan inwardly extending supporting bead 2 situated a short distance above the lower edge, and reinforcing beads 3 arranged at 'its upper and lower edges. Shell l i's provided with a lifting bail 4 of ordinary construction and is linedl with double layers of asbestos paper 5, as shown. A bottom 6 is provided with n :merous perforations or other foramin'ations 7 and is loosely inserted in shell 1 to be supported by bead 2 as shown.

An inner food containing vessel 8 is made of earthen ware, pottery, porcelain or other ceramic material and fitted within shell 1, as shown. Vessel 8 is made downwardly tapering in form and is provided with an outwardly extending lip 9 at its upper edge .which will limit the extent of insertion. of

said vessel in shell 1. Vessel 8 is provided with a removable lid or cover' 10 made'out of the same material as said vessel. Lid`10 is provided with a perforation 11 to permit the escape of steam from said vessel during cooking. Vessel. 8 and lid 10 are glazed on the inner, but not outersides. It will beobserved that the depth of vessel 8 and its insertion into shell lis such that ahot air chamberlQ is formed under and around vessel 8. Said vessel and cover are made of the same' material and of a substantially uniform thickness, being made thick enough to cause the walls and cover to constitute radiators, and thus dispense with the use of the usual radiators employed in tireless cookers. Ihe air chamber under and around vessel 8 insures uniform and gradual application of the heat thereto so that said vessel will not the cooking operation, ottorn 6 insures a unipreferred form of construct-iony for carry-ly ing my invention into effect, this is capable otvariation and modification without departing from the spirit of the' invention. 'L therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and A.modifications as come within the scope of the appended claims.-

i Having described my invention what I claim as new and desire to secure by Letters Patent is:

l. A cooking utensil comprising an outer cylindrical metallic shell having an inwardly extending` bead situated above the bottom` asY edge thereof;- an asbestos lining forsaid f outer shell; a foraminated bottom supported by said bead; and an inner downwardly tapering ceramic ware vessel fitting within said shell and supported thereby, substantially as described.

2.. An article of manufacture comprising an outer cylinder open/at bothends; reinforcing means formed at the ends ofV said cylinder; an inwardly extending supportin 'bead formed inthebo'dy of the cylinder a jacent to and spaced from the lower edge thereof; a plurality of sheets of asbestos l.mounted upon the interior of said cylinder and adapted to conformxwith the contour thereof, accomodating the supporting bead aforesaid; an apertured plte arranged upon name to his speeeatiol in the presence of by suld bead; and an' lnner downwardly two snhsmlhmg wltnesses. sand supportn'lg bend; und. nn nmer vessel mounted inthe upper end of said cylinder CHARLES DAVIES FRAQUNFEITEI having' the bottom thereof spaced from the Witnesses: plate.
